Interesting idea, but actually, the suits don't work that way. They require positive pressure on the inside, and vent out. Further, one of the not so pleasant and not well advertised effects of most VHF's is bloody discharge and serious diarrhea.
Somehow I doubt the OP was considering a positive pressure suit with SCBA. Those are extremely rare for bio hazards. And extremely expensive.
And I think the "discharge" issue is common knowledge.
But the most important point, it was a joke.
